Improved roller-skate



UNITED STATES PATENT OFFICE.

IMPROVED ROLLER-SKATE.

Specification forming part of Letters Patent N0. 48,929, (lated July 25, 1865.

To all whom it may concern:

Be it known that I, WASHINGTON PARKER GREGG, of Boston, in the county of Suffolk and State ot' Massachusetts, have invented a new and useful ImproyementinRoller-Skates; and

I do hereby declare that the following description, with the accompanying drawings, forms a i'ull, clear, and exact specilication thereof.

My improvement consists in a novel construction of the roller-skate.

The accompanying drawings exhibit the stock and rollers ot a skate embodying my improvements.

Of such drawings, Figure l exhibits the skate in top View; Fig. 2, in side elevation; Fig. 3, in longitudinal section, and Fig. 4 in transverse section.

In carrying out my invention I make the stock A of the skate of either metal or wood, of any suitable form, and with any simple attachments for fastening it to the foot ot'aperson, combiningr lightness, strength, and security.

I arrange two comparatively small rollers, B B, for support, one partly under theheel and the other partly under the toe of the stock, and I also arrange two comparatively large rollers, G C, for driving, one-on each side of the stock under the arch of the foot, near the line Ot' gravity of the skater. I make the rollers, their axles and connections or fastenings, of metal or wood, or partly Ot' both, solid or otherwise,

. securing strength, lightness, and durability.

The size of the stock is adapted to the foot, and the size of the rollers may be varied accordin gto the skill of the skater and the quality of the skatin g surface.

For common purposes the smaller rollers may be three inches in diameter and one inch in width on the periphery, and the larger rollers may be five inches in diameter and one inch in width on the periphery.

The axles or journals ofthe side rollers project from the stock. These rollers enable the skate to run with greater ease and rapidity than it could by means ot' the heel and toe rollers alone. They are so arranged that their peripheries or the bearing-surfaces thereof shall be a little lower than those of the heel and toe rollers, in order that the skater while skating may drive himself almost entirely by the large rollers.

Roller-skates thus constructed run with ease and rapidity, and do not injuriously sprain the feet nor weary the limbs, and they will not easily tip backward or forward, and they impart from the rst an unusual feeling of security to the skater in all possible movements.

This skate is well adapted to hard sidewalks, large halls, gymnasiums, and skatingschools, and in suitable places for traveling purposes.

I claim- A roller-skate constructed with a stock having a small supporting-roller under each end and a. large driving-roller ou each side, substantially as described.

WASHINGTON PARKER GREGG.
